Description
Technical field
The present invention relates to building energy conservation and photoelectricity building field, relate to a kind of photovoltaic building materials that are applied to the BIPV (Building Integrated PV) building, be specifically related to a kind of roofing photovoltaic waterproof roll and preparation method thereof.
Background technology
Traditional roofing is only the function of becalming and taking shelter from rain, and long-term exposing to the sun and rain causes building roof waterproof layer aging damage, and it had both reduced the use function of building, has reduced the application life of building, has wasted again a large amount of sunlight resources.How to make sunshine change into advantageous effect to the adverse effect of building, change sunshine into inexhaustible regenerative resource, meet the demand of green building to roof waterproof, prolongation building application life and the required electric power of generating power for their own use, become the important research content of photoelectricity building field.
Roofing is solar energy utilization occasion the most easily and effectively, is that photovoltaic generation is in architectural preferred location.The form that roofing photovoltaic generating at present mainly takes to install the crystal silicon photovoltaic cell panel, the crystal silicon photovoltaic cell panel is arranged on building roof two kinds of fixed forms usually: a kind of is to utilize deadweight or increase ballast, directly be placed on roofing, because load is large, on light roof and long-span roofing, can't apply, exposing also difficult application on water-proof roofing, produce normal pressure because the component of tilting ballast cell panel can expose coiled material to roofing in addition, long term can destroy roof waterproof layer; Another kind of fixed form is that fixture penetrates the rolled roofing material waterproofing course, and roof construction layer fixes, and can destroy waterproofing course like this, and infiltration hidden danger is arranged, and does not meet the basic principle of waterproof.Above two kinds of fixing meanss all exist wind the potential safety hazard such as to take off.The unfavorable factors such as crystal silicon photovoltaic cell panel installation system, except the destruction existed waterproofing course, also exists increase building bearing and high-rise wind to take off risk, and the impact building is attractive in appearance.
The photovoltaic film battery assemblies such as non-crystalline silicon belong to second generation photovoltaic cell, it has following technical characterstic: 1, light matter and thin body; But 2, the good flexing of pliability, be suitable for various special opposite sex surface; 3, the low light level, scattered light, diffused light absorptive capacity are strong; 4, mat formation simple and easy to do, can with any substrate compoiste adhering.At present existing correlation technique is on-the-spot bonding with waterproof rolls such as TPO, EPDM, EPDM rubber waterproof rolling material or thermoplastic polyolefin waterproof roll modified bitumens at water-proof roofing by flexible solar photovoltaic film battery components such as non-crystalline silicons, form photovoltaic waterproof roll roofing, but there is the execute-in-place complexity in this technique, quality is affected greatly by environment and human factor, the problems such as comprehensive cost height.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of roofing photovoltaic waterproof roll and preparation method thereof, described roofing photovoltaic waterproof roll both can be used as waterproof roll, can carry out photovoltaic generation again, the functional photovoltaic building materials component required for meeting BIPV (Building Integrated PV).
A kind of roofing photovoltaic waterproof roll, described roofing photovoltaic waterproof roll is layer structure, comprises successively from the inside to the outside waterproof roll base material, fexible film photovoltaic cell component, rete and dope layer.
Roofing photovoltaic waterproof roll of the present invention, wherein said waterproof roll base material is EPDM rubber waterproof rolling material or thermoplastic polyolefin waterproof roll.
Appropriate butyl rubber, vulcanizing agent, accelerator, softening agent and reinforcing agent etc. mix with ethylene propylene diene rubber in EPDM rubber waterproof rolling material system, process through operations such as banburying, pulling-on piece filtration, extrusion moldings.This waterproof roll has excellent against weather, resistance to ag(e)ing, and also tensile strength is high, elongation per unit length is large, flexible to basic unit or ftracture strong adaptability, lightweight, serviceability temperature wide ranges (can use for a long time in-40～+ 80 ℃ of scopes), be a kind of high-effective water-proof material.It also can coldly be constructed, easy and simple to handle, and environmental contamination reduction improves workman's condition of labor, and EPDM rubber waterproof rolling material belongs to high-grade waterproofing materials, is applicable to roofworks and exposes waterproof as individual layer, also is applicable to the roof waterproof engineering of matcoveredn.
